Cattle-guard



NITED STATES? I BENJAMIN VVOLI-IAUPTER, OF MORGAN PARK, ILLINOIS.

CATTLE-GUARD.

- SPEGIFIGATION forming part of Letters Patent No. 505,867, datedOctober 3, 1893.

Application filed January 21, 1893. Serial No. 459,064. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN WOLHAUPT- ER, a subject of the Queen ofGreat Britain, residing at Morgan Park, county of Cook, State ofIllinois, have invented a certain new and useful Improvement inCattle-Guards; and I declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention has for its object the provision of a metallic cattle guardwhich shall be simple, durable and cheaply manufactured.

The invention is a direct improvement on the cattle guard shown in aprevious patent issued to me March 3, 1891, No. 447,394.

It consists of a combination of devices and appliances hereinafterdescribed and claimed.

In the drawings: Figure 1 is a longitudinal section of the guard on aline parallel with the track rails. Fig. 2 is a cross section. Figs. 3,4, 5 and 6 show the manner of securing the ends of the guard bars. Figs.7, 8 and 9 show variations in the form of the cross bars.

In carrying out my invention A represents the longitudinal or guard barsof my guard which as in my previous patent are provided on the upperedge with an overhanging flange a. The body of the guard is inclined asshown so that this overhanging flange presents a downwardly projectingedge (not necessarily sharp however) above the plane of the lower edgeof the bar next adjacent. Onthe lower edge of each longitudinal bar is aflange a preferably, for convenience in manufacture, and lateralstrength extending in the direction opposite to the flange a. Thisflange may be located at any convenient angle to the main body of theguard, but I prefer that shown in Fig. 2. In order to support thelongitudinal bars in their proper inclined position and to give strengthand rigidity to the structure I provide the cross bars B. These crossbars may be of any suitable cross section, so long as there are one ormore upright portions I) having inclined slots 1) to receive the body ofthe longitudinal bars.

The lower end of each of these slots is provided with a notch or recessinto which the flange a projects and by which the flange is held. Thuswhen the longitudinal bar is slipped into this slot it is held by theflange from upward movement. As I said above the cross bars may be ofany suitable crosssection, but'I prefer to make them of an inverted Vshape as shown in Figs. 1, 2, 3, 4, 5, and .6. When made in this shapethey are provided with flanges b through which suitable fasteningdevices may be passed to secure the cross bars to the ties. Or theseflanges might be turned down as shown in Fig. 9 and extend down betweenthe ties.

To prevent longitudinal movement of the guard bars I extend the ends ofthe guard bars through one upright portion b of the end cross bars, butnot through the other. The metal on the end of the guard bar may then beturned at an angle to the body of the bar in any desired direction. InFigs. 3 and 4 I have shown it turned in one direction as at a and inFig. 5 I have shown it turned in the opposite direction at c Theconstruction wherein the end of the guard bar is turned may be employedwhere the end cross bars are not attached to the ties. Where the endcross bars are attached to the ties the end of the longitudinal bar maybe extended only into the cross bar Without turning of the metal on theend as in Fig. 1. Or if desirable a bolt 0 may be employed extendinglongitudinally through the cross bar and transversely through the end ofeach guard bar, the bolt being properly secured at each end. While Ihave shown in Fig. 8 a form of cross bar in which there is but oneupwardly projecting flange it is obvious that such a form would beconvenient for use more particularly for one or more of the middle crossbars, that is to say such a form could not be conveniently used for anend cross bar without a bolt or some other fastening to secure the endof the guard bar to the cross bar.

I am aware that it is not broadly new to extend guard bars transverselythrough slots in the cross bars, and such a construction I do notbroadly claim, but

What I claim is- 1. In a cattle guard the combination of inclined guardbars and cross bars provided with inclined slots through which the guardbars extend, the wall of each slot provided with a recess into whichenters a flange located adjacent to the lower edge of the guard bar andmeans for preventing a longitudinal movement of the guard bar,substantially as described.

2. In a cattle guard the combination of inclined guard bars providedadjacent to the upper edge with aflange extending at an angle from thebody of the bar and cross bars provided with inclined slots throughwhich the longitudinal bars are passed the wall at the lower end of eachslot being provided with a recess into which enters a flange on thelower edge of each cross bar, and means at the end of each guard bar forpreventing a longitudinal displacement of the guard bars, substantiallyas described.

3. In a cattle guard the combination of inclined guard bars each onehaving on its upper edge a flange which extends substantially at a rightangle to the body of the guard bar, and on the lower edge another flangewhich extends in the opposite direction, and cross bars provided withinclined slots so shaped as to receive the body and the lower flange ofthe guard bar, the ends of each' guard bar being passed into, but notthrough the cross bar at each end, substantially as described.

4. In a cattle guard the combination of inolined cross bars eachprovided with a flange on its upper and lower edges and cross barsprovided with inclined slots adapted to embrace and hold the guard barsagainst upward displacement, the ends of said guard bars being passedinto but not through the cross bars at the end, and the metal on theends of each longitudinal bar being turned at an angle to hold the guardbar against longitudinal displacement, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
